I'm trying to serve my website via https, so I need to install an SSL certificate.
Not sure if this is relevant info, but I have several domains in this server, one of which has a certificate installed.
Since the website is ran by wordpress, I installed the "WP Let'sEncrypt" plugin in order to get a free SSL (that expires in 90 days). I did that and the plugin created a "keys" folder and a ".well-known" folder.
I downloaded 3 files from the plugin, a cert file, key file and ca bundle. I tried to install these following the video from the plugin ( https://www.youtube.com/watch?v=_PRP2vXr73g ) but my hosting provider (dina-hosting) doesn't have an option to install SSL certificates. I asked them directly and they told me it would be 45 euros + taxes for the procedure, which I find to be too much.
So, my question is how can I install this certificate? I have ftp and ssh access to the server. Is there a better (free) way of doing this?
